Specification of Letters Patent.

Patented Jan. 30, 1906.

To all whom it may concern:

Be it known that I, JAMES DONOVAN, a citizen of the United States, residing at Three Rivers, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements inIIand-Car Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to frames for light cars-such as hand-cars, push-cars, &c.\; and it consists in a metallic frame which is strong, and chea ly constructed, also in a frame made of s ieet metal and preferably struck from a single piece comprising sills rangement of the various par'ts,'as more fully hereinafter described, and particularly points ed out in the claims.

In the drawings, Figure 1 is a perspective view of a hand-car frame embodying my invention. Fig. 2 is a crosssection thereof on linegc ac. .Fig. 3 is a section on line y y. Fig. 4 is a section through one of the axle-boxes to show-the manner of connecting the axle to the frame; and Fig. 5 is portion of the frame, showing the front axletwo end ties O and intermediate ties.

box bracket.

In. making my frame, as particularly herein illustrated, I-take a single sheet of metal of size suflicient to make the entire frame and with suitable dies shape it as shown in Fig. 1, consisting of the side sills A, the two intermediate sills B, and ties connectin the sills. These ties for the hand-car are pre erably the I have shown three intermediate ties, those near the endsE extending in line clear across and the middle tie com rising the two side sections at and the middle section b offset from the line of the sectionsa to form the wall or opening F, over which the gallows-frame stands, the base of this frame bein indicated at G- The sills and ties I. prefera bly flan e, orformin the shape of channels,

a side elevation of a andv t s may be done in a single pressing operation between dies, at the same time the metal between the sills and cross-sills and ties being I struck out-.'- The side sills I preferably make deeperthan'theintermediate portion of the frame, as by forming the channel portion '0 above the'plane of the intermediate frame portion, the side cl extending down below the 1ntermediate channels. This allows one to secure the flooring H on the frame between the channels c of the side sills and substantially flush therewith. The outer faces of the end ties'C, I practically extend down flush with the sides cl of the side sills.

I represents stiffening members for the frame. I prefer to extend these through the channels in the sills, as shown, using pipe or tubes, and extend them through apertures in the end ties, letting them project to form handles J, by which the car may be lifted about. The bolts K, which secure the gallows-frame in position, passing through the two intermediate pipes wise displacement. I

L represents blocks or brackets secured by lateral bolts M, which ass through the sides at and through the si e pi es I and which have the journal-bearings thereon for the axlesP, having wheels Q, as usual. I also eep them from endem loythe vertical bolts R for these blocks all j ournal-bearings.

While I have shown and prefer to make the frame from a single sheet of metal, I believe in certain features my invention includes other ways of making the frame.

Instead of cutting out all of the metal between the sills I may simply depress one or more sectionssuch,' for instance, as shown at S-and form these sections with the bottom plate T to make receptacles for tools, the floor being omitted from over such sections.

What I claim as m invention is 1. In a light car, a rame comprising longitudinal sills and ties, struck from a single sheet of metal.

2. In alight car, a frame comprising side sills, two separated intermediate sills, and connecting-ties, struck from a single sheet of metal.

3. In a light car, a frame comprising .inverted channel-sills and ties, struck from a single piece of metal.

4. In alight car, a frame'comfirising sheet-;

metal intermediate sills, latera y-ex'tending integral ties and side sills, the ties connecting to the side sills below the top thereof.

5. In alight car, a frame formed of a single sheet of metal and comprising longitudinal intermediate sills, ties and side sills, the ties connecting to the side sills below the top.

6. In alight car, a frame, longitudinal inverted channel-sills, longitudinal stiffening members, secured in the channel, and ties connectin the sills.

7. In aIight car, a sheet-metal frame comprising inverted channel sills and ties, and tuular stifienin members extending through the channels 0 the sills. I

8. In a light car, a frame comprising inverted channel sills and ties, struck from a single piece of sheet metal, and stiffenin tub filar members secured in the channels 0 the s1 s.

9. In alight car, a frame comprising sills and ties in inverted channel form, struck from a single sheet of metal, stiffening-bars extending through the channels of the sills, and through the sides of the end ties.
